LEATHER STUFFIN G AND FULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,321, dated August 9, 1881.

Application filed January 18, 1881. (No model.)

To all whom it may concern.-

Be it known that I, JoHN A. J. SHULTZ, of St. Louis, Missouri, have made a new and useful Improvement in Leather Stuffing and Fulling Machines, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which-'- Figure 1 is a plan of the improved machine, a portion of the stuffing-cylinder being broken. away; Fig. 2, a side elevation; Fig.3, an end elevation; Fig. 4, a section, taken on the line 00 00 of Fig. 2; Fig. 5, a detail, being an elevation, looking in the direction of the arrow, of Fig. 1, and showing the lever and parts immediately therewith connected, of the shifting mechanism, and Fig. 6 a cross-section taken on the line 1 of Fig. 1.

The same letters denote the same parts.

I have heretofore (May 16, 1876) patented an improvement in leather stuffing and fulling machines.

The present invention is an improvement upon the construction referred to, the improvement relating partly to the means for confiningand cramping the leather in a longitudinal direction in the stuffing cylinder or trough during the stuffingoperation, and partly to the mechanism employed in changing the direction of the rotation of the cylinder-shaft.

Referring to the drawings, A represents the cylinder wherein the leather is stuffed, and B the cylinder-shaft to which the leather is fastened, and by means of which the leather is rotated and worked within the cylinder. These parts-the cylinder and shaft-are, saving as modified by the cramping mechanism in question, substantially the same as in the original construction.

E E represent followers movable longitudinally on the shaft B, being spaced sufficiently apart thereon to receive between them the leather that is attached to the shaft. The followers are connected together so as to properly confine the leather longitudinally in the cylinder, the connections, however, being elastic, in order to yield and elongate and allow the followers to open whenever an unusual strain, as when the leather in its working becomes unusually bunched or knotted, comes upon them, and to contract again and draw the followers toward each other into their original positions as soon as the strain is relieved.

The connecting devicesare shownat F F at each side of the cylinder, and" connecting with the arms 6 0, with which the followers are furnished, and which project through or beyond the shell of the cylinder. The devices F F, more particularly described, are as follows: rods ff, at their outer ends, are held in the arms 0 e, and at their inner ends are respectively provided with, or made in the form of, the partsf f The latter are respectively furnished with projections f f which interlock similarly to aclutch. Abearing,f is attached to the ends of the projections ffland a si milar bearing,f to the ends of the projections f Springsj' f are arranged between the bearings f f and act to press the bearings apart, and in so doing to draw the followers together. The bearings f f" may bein the form of handwheels, as shown in Figs. 1,2, 6, and the rods ff are threaded, so as to screw into the parts f f This last-described feature enables the followers to be readily relatively adjusted, for by turning the hand-wheels and clutches upon the rods the devices F F are elongated or shortened, as the case may be. For this purpose the threads upon the rods ff run in opposite directions, and the rods, in their bearings in the arms e e, are squared to prevent their being turned.

The improved mechanism for changing the direction of the rotation of the cylinder-shaft is as follows: As in the original construction, a pulley, J, is arranged on a shaft, I, upon the inner end of which is a pinion, H, engaging with a gear, G, upon an extension of the shaft B. The gear G also engages with a pinion, K, that is attached to a shaft, L, which is threaded at l. A nut, O, is upon this threaded portion .1, and by the time the shaft B has made the proper number of revolutions in one direction the not has been caused to travel on the shaft L sufficient] y to move the lever Q, and thereby the slide B. This shifts the driving-belt onto the pulley J. The motion is then transmitted through the shaft S, (to which the pulley J is attached,) gear-wheels S L, shaft L, and pinion K, to the gear Gr, causing the latter to rotate in the opposite direction. The not 0 now travels in the opposite direction until the lever Q has been thrown over into its original position, when the operation is repeated, and so on.

To prevent the nut 0 from rotating with the shaft L the nut is provided with an arm, 0, which travels in a guide, 0, and to operate the lever Q the nut is furnished with an arm, 0 which engages with the projections q q upon or connected with the lever Qthat is, in 1110 ving in one direction the arm 0 presses against the projection q, and in moving in the other direction it presses against the projection q. The latter is connected with the slide R by means ofthe rod R. The slide R has the usual arms, 1' 1', for shifting the belt.

It will be seen that the shaft N of the original construction is dispensed with and the mechanism otherwise simplified.

I claim 1. The combination of the cylinder A, followers E E, and connections F F, substantially as described.

2. The combination of the rods f f, parts f 2 f projections f f, bearin gs j j, and spring f substantially as described.

3. The combination of the parts f f projections f f bearings jf, and spring f, substantially as described.

4. The combination of the hand-wheels f f", rodsff, partsf f projectionsff springf, and arms a a, substantially as described.

5. The combination of the cylinderA and the followers E E, said followers bein g connected together by means of elastic connections.

6. The combination of the pulleys J J, shafts I B L S, gears H G S L K, nut O, lever Q, and slide R, substantially as described.
